4 Claims.

This invention relates to a particularly simple, effective and novel iceremover for Windshields. The collection of ice at the outer side ofwindshields in motor vehicles at times during the colder seasons of theyear is a matter of consid erable danger in driving. The ice adhe esstrongly to the glass and has been difllcult to remove except with theuse of sharp steel instruments, for example, razor blades properly heldfor cutting and removing the ice. Such sharp steel implements, howevereffective they may be for ice removal, scratch and otherwise damage thesurface of the glass. With my invention the ice is very quickly andexpeditiously removed without danger of abrading the glass surface. Theimplement which I have devised may be made in different forms, for usewhen the ice frozen to the glass is in a relatively thin or thickdeposit and, for convenience, two different forms which I have" devisedfor the two different conditions mentioned may be readily connectedtogether so that either may be used in accordance with the conditionmet. 7

The invention may be understood from the following description taken inconnection with the accompanying drawing, in which,

Fig. 1 is an elevation showing a portion of a windshield in section, andillustrating the manner in which the ice removing tool or implement maybe used in removal of a thinice coating.

Fig. 2 is an enlarged longitudinal section through the ice removingimplement.

Fig. 3 is a plan view thereof, and

Fig. 4 is an under view.

Like reference characters refer to like parts in the different figuresof the drawing.

In a preferred construction of the ice removing implement two members Iand 2, preferably of hard rubber, are connected together, the upper endof the part 2 being reduced in diameter and exteriorly threaded asindicated at 3. The upper portion I consists in effect of a cylindricalsleeve of the same material which has a downwardly extending section 4below an integral cross web 5 extending across the interior of thesleeve, which downward extension is interiorly threaded and may bescrewed upon the exterior threaded part 3 to connect the two parts I and2.

Above the cross web or partition 5, the upper member I has a recess 6surrounded by a cylindrical wall I. The exterior surface of the member iis corrugated, that is, provided with a continuous series of verticallyextending ribs 8 separated by vertical grooves or valleys between theribs.

The lower portion of the member 2 is flared outwardly and downwardly,providing a continuous annular bell-like wall 9 around an interiorrecess ID. The lower edges of the wall 8 are curved downwardly andinwardly as at H, meeting with the lower parts of the interior recesssides to provide a relatively sharp continuous annular edge at l2, asshown.

The windshield glass it) is indicated in Fig. 1 as having deposited at aside thereof a thin layer of ice l4. Where the ice coating is relativelythin the lower member 2 is brought against the ice and the cutting edgeat I! will pass therethrough and then by moving the implement laterallyover the surface of the glass the ice will be scraped ahead of the sharpedge 12 and forced outwardly between such edge I2 and the curved edgesat H. When the ice is relatively thick the implement is reversed inposition and the corrugated outer edges of the wall I of the uppermember I are forced into the ice and will cut therethrough more readilythan the edge at l2, and will scrape and remove the ice from the glasswindshield.

The material used which preferably is hard rubber, or of an equivalentnature, does not scratch or abrade the glass yet it cuts the ice andscrapes and removes it from the glass very quickly and cleanly.

It is of course to be understood that the specific .constructiondisclosed shows two of the forms only in which this invention may beembodied. There are numerous other ways in which it can be constructedto obtain the scraping edge at l2 with the outwardly curved or flaredsurface I l in conjunction therewith; also to obtain a corrugated edgefor engagement and removal of the thicker deposits of ice. Theconstruction does not have to be in the circular or conical form shownbut may take numerous other forms.

The invention is defined in the appended claims and is to be consideredcomprehensive of all forms of structure coming within their scope.

I claim:

1. An ice scraping implement of a hard plastic material, said materialhaving a degree of hardness between that of ice and glass and providedwith a wall having an annular scraping edge,

the sides of which are located in angular relation to each other.

2. An ice removing implement adapted for scraping ice frozen to thesurface of glass comprising, a member having a wall and a scraping edgeformed by two sides of said member joining at a corner to provide saidscraping edge, said implement adjacent the scraping edge being 01 amaterial having a hardness that the scraping edge will penetrate icefrozen on glass and not hard enough to scratch the glassflthe outer sideof the wall, to be presented to and forced against the ice, beingserrated to provide spaced apart ribs with intervening grooves betweenthe ribs, as and for the purposes specified.

3. An ice scraping implement of a hard plastic material, the degree ofhardness of which is less than that of glass and sufficiently hard topenetrate ice frozen on glass, including an annular wall having a freeedge and provided with an ice penetrating and scraping annular portionaround it for engaging with and removing ice frozen to a glass surface,by forced movement oi. said scraping edge against the ice.

4. An ice scraping device comprising, a hollow member of substantiallycircular form in cross section, having the lower portion thereof flaredoutwardly, the inner and outer sides of said member being broughttogether to form a 'sharp edge, said device being formed of a hardplastic having a lesser degree of hardness than glass and greater thanice.
